"heroku run fileName" after grunt build

To learn more about heroku scheduling I read this post and built the app described in it. The key part of this post was when I was able to heroku run numCheck and the code within the numCheck file executed. After testing that heroku run numCheck worked I was able to schedule regularly occurring events in Heroku just fine.

I used yo angular-fullstack to create my app, Angel Insights and it's functional. However I want to add in heroku scheduling capabilities but I'm getting stuck. My problem is that I cannot run heroku run refresh in the Dist folder after I've run grunt build. Here's what I've tried specifically...

1. Added bin/refresh before Grunt build (refresh code below)
2. Added bin/refresh directly into the Dist folder after grunt build
3. Tried heroku run anyFile after git push heroku master with both attempts

#!/usr/bin/env node
var sendgrid  = require('sendgrid')(
  process.env.SENDGRID_USERNAME,
  process.env.SENDGRID_PASSWORD
);

var num1 = Math.ceil(Math.random() * 100);
var num2 = Math.ceil(Math.random() * 100);
var comparator;

if (num1 > num2) {
    comparator = "greater than";
} else if (num1 < num2) {
    comparator = "less than";
} else {
    comparator = "equal to";
}

sendgrid.send({
    to: 'andrewscheuermann@gmail.com',
    from: 'scheduler@tester.com',
    subject: 'Num1 v Num2',
    text: (num1 + ' is ' + comparator + " " + num2 + ".")
  }, function(err, json) {
    if (err) {
      console.error(err);
}

I'm really stuck and any insights are extremely appreciated!
